v-model changes about core

[posva]

Regarding the type="checkbox", I was thinking we could add some modifier to handle it (not sure about the naming) .checkbox, .number. That way it doesn't collide with props, although it looks less similar to regular inputs.

Regarding the default value modelValue, is there a reason not to keep the default prop to value? I think in both cases, we won't be able to help well with a migration tool and it could reduce the migration too. I do think it's a good idea to have update:value as a new default though

Because the idea is to move element/input type specific handling to the runtime, so the v-model output must be something special for the runtime to pick up and transform. If we use the default value and input, the runtime won't know if it's created by v-model or manually by the user.
